EN Standard Steel Plate

The EN 10025: 2004 encompasses a broader range of structural metallic products and divides them into six basic categories:

General Purpose Steels

Non-alloy Structural Steels

Normalized / Normalized-Rolled Weldable Fine Grain Structural Steels

Thermo Mechanically-Rolled Weldable Fine Grain Structural Steel

Atmospheric Corrosion Resistant Structural Steel ("Weathering Steel")

High Strength, Quenched and Tempered Structural Steel

Within these six categories are individual grades. The foundation of each grade within the EN 10025 standard is the material’s tested yield strength measured in megapascals (1 MPa = .145 ksi). Each structural steel grade begins with an "S" and is followed by suffixes that represent variations in the specific requirement for that structural application.
